Abstract
Abstract Internet access is provided to a multimedia terminal (101, 102, 103, 104) supporting the H.320 protocol through a gateway server (125) that is connected to the Internet. The data stream of the H.320 bearer channel (ISDN phone line or switched 56 kbps facilities) is used for the exchange of data between the accessing terminal and the gateway server, which outputs and receives such data onto and from the Internet, respectively. The gateway server is implemented to function to directly exchange on the H.320 data stream information requests and responsive data in the TCP/IP format used for Internet transport. Alternatively, the gateway server is implemented to function as a proxy to which requests are passed from the terminal over the H.320 data stream, and where function calls are made and locally converted to TCP/IP format for transport onto the Internet. For responsive data received from the Internet, the proxy gateway server removes the TCP/IP formatting and transmits the resultant data back to the terminal over the H.320 data stream.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
89 words
In a telecommunications network, a method of providing Internet access to a multimedia terminal capable of communicating voice, video and data over separate voice, video and data streams, respectively, of a bearer channel, the method comprising the steps of: establishing a connection between the terminal and a gateway server over the bearer channel; passing a request received by the gateway server from the terminal over the data stream to the Internet; and passing information received by the gateway server from the Internet to the terminal over the data stream.
Claim 2
Dependent Claim
22 words
The method of claim 1 wherein the connection between the terminal and the gateway server operates in accordance with an H.320 protocol.
Claim 3
Dependent Claim
40 words
The method of claim 1 wherein the request received by the gateway server from the terminal is received in a format compatible for transmission on the Internet and the gateway server passes that request to the Internet in that format.
Claim 4
Dependent Claim
32 words
The method of claim 3 wherein the information received by the gateway server from the Internet is passed to the terminal over the data stream in the format that it is received.
Claim 5
Dependent Claim
44 words
The method of claim 1 wherein prior to the step of passing a request received by the gateway server from the terminal to the Internet, the method further comprises the step of converting the request to a format compatible for transmission on the Internet.
Claim 6
Dependent Claim
32 words
The method of claim 1 further comprising the step of compressing the information received by the gateway server from the Internet before it is passed to the terminal over the data stream.
Claim 7
Dependent Claim
22 words
The method of claim 6 further comprising the step of decompressing a compressed request received by the gateway server from the terminal.
Claim 8
Dependent Claim
40 words
The method of claim 1 when after the step of establishing a connection, the method further comprises the step of adjusting the bandwidth of the data stream to be larger than the bandwidths of either the voice or video streams.
Claim 9
Independent Claim
139 words
A system in a switched telecommunications network for providing Internet access to a multimedia terminal capable of communicating voice, video and data over separate voice, video and data streams, respectively, of a bearer channel, the system comprising: a gateway server; a first communications path in the switched telecommunications network for connecting the terminal to said gateway server over the bearer channel; and a second communications path connecting said gateway server to the Internet; said gateway server passing a request received from the terminal over the data stream of the bearer channel of the first communications path to said second communications path for transmission onto the Internet, and passing information received from the Internet on said second communications path onto the bearer channel of the first communications path for transmission of the information to the terminal over the data stream.
Claim 10
Dependent Claim
24 words
The system of claim 9 wherein the first communications path between the terminal and said gateway server operates in accordance with an H.320 protocol.
Claim 11
Dependent Claim
44 words
The system of claim 9 wherein the request received by said gateway server from the terminal over the data stream is received in a format compatible for transmission on the Internet, and said gateway server passes that request to the Internet in that format.
Claim 12
Dependent Claim
39 words
The system of claim 11 wherein the information received on said second communications from the Internet is passed by said gateway server to the first communications path for transmission to the terminal in the same format it is received.
Claim 13
Dependent Claim
36 words
The system of claim 9 wherein a request received over the data stream on the first communications path from the terminal is converted by said gateway server to a format compatible for transmission on the Internet.
Claim 14
Dependent Claim
30 words
The system of claim 9 further comprising means for compressing the information received by the gateway server from the Internet before passing it to the terminal over the data stream.
Claim 15
Dependent Claim
26 words
The system of claim 14 further comprising means for decompressing a compressed request received by the gateway server from the terminal on the first communications path.
